I just received my RC522 RFID reader and made this simple Arduino access control system that uses the reader, a buzzer for the alarm and a relay shield for the security system. The relay can be used ...

[Matt] has mixed up a batch of two RFID reading door lock systems. While the “door lock” part of the setup has yet to come into existence, the “RFID reading” section is up and running. By using the ...

RFID Module: Reads the UID from an RFID tag/card. If the UID matches the authorized UID, access is granted. This project is open-source and can be freely used for educational purposes. I demonstrate ...

The use of Radio Frequency IDentification (RFID) technologies is growing. Many different applications are implemented in various sectors, and used for very different purposes. RFID enables wireless ...

This project implements an RFID-based access control system using an Arduino board, an MFRC522 RFID reader, an I2C LCD display, an RTC (Real-Time Clock) module, and indicator LEDs with a buzzer. It ...

The radio frequency identification (RFID) system used for the identification and tracking of objects makes use of an RFID reader and a tag. The main parts of the authentication system include the ...

Arduino RFID projects have become increasingly popular in recent years due to the simplified technological mechanisms provided by the Arduino platform. The integration of RFID technology with Arduino ...

Radio Frequency Identification (RFID) technology is a system capable of identifying objects through a unique identifier (UID). The RFID system consists of two main components: an RFID tag and an RFID ...

RFID stands for Radio-Frequency Identification — a wireless technology covering devices for security, access, and goods tracking purposes. In essence, an RFID system includes an RFID reader and one or ...
